I have extensive experience building hardware accelerated AI inference pipelines on Windows, including on the now retired DirectML (not a great loss). One thing I learned is that the hardware vendor support promised in press released is often an outright lie, and that reporting any kinds of bugs or missing functionality will only result in a infinite blame game loop between Microsoft developer support and the hardware vendors. It appears that Windows is no longer a platform that anyone feels responsible for or takes pride in maintaining, so your best hope is to build a web app on top of Chromium, so that at least you will have Google on your side when something inevitably breaks.
